Synthesis of fibronectin by the isolated perfused rat liver

Synthesis of fibronectin by the isolated perfused rat liver.

The major site(s) of synthesis of plasma fibronectin is unknown. Using the isolated perfused rat liver and anti-rat fibronectin antiserum, we have measured net hepatic synthesis of fibronectin during 10-hr perfusion periods. We calculated the circulating plasma fibronectin pool of a 195-g rat with body surface area of 300 sq cm to be 3.3 mg: net hepatic synthesis of 3.75 +/- 1.0 mg/300 sq cm bo...

SEQUESTRATION OF LEUKOCYTES BY THE ISOLATED PERFUSED RAT LUNG

The sequestration of rat leukocytes and bone marrow cells by the lung vasculature was studied using an isolated perfused rat lung preparation. The passage of latex particles of 7.6 µm in diameter and non-hematopoietic cells through the lung blood vessels was also studied. Leukocytes and bone marrow cells were reversibly sequestered from circulation, whereas, latex particles and non-hematop...

The isolated perfused rat liver.

The disposition of mefloquine has been investigated in the isolated perfused rat liver (IPRL) preparation after the administration of [C]mefloquine HCI (3.8 mg, 4 1 Ci, quinoline ring labeled). Mefloquine underwent avid hepatic uptake within 10 min of dosing. Also at this point, hepatic oxygen consumption was reduced markedly in four of the six IPRL preparations, but was restored completely by ...

Induction and Synthesis of Metallothionein in Isolated Perfused Rat Liver*

The induction and synthesis of metallothionein was studied in the isolated perfused rat liver, using Cd(I1) as the inducing metal. Perfusing the liver with 25 to 100 pg of Cd(I1) for 180 min revealed that the amount of Cd(I1) in metallothionein increased with the dosage of Cd(II), saturation being achieved at 75 pg. Zn(I1) in metallothionein decreased to about 60% of the level found in control ...
